she has probbaly turned off teh wireless adapter

there will be either a button that slides across on teh laptop with what looks liek a satelite dish which you slide to on ( it may slide back on its own but will be enabled)

or

there will be a button that has "fn" written on it usually in blue , hold this button down and press another key which will have a picture of what looks like a cocktail glass on it also in ble - usually along teh top row but could be on one of teh other keys

this will enable the wireless adapter nad you will be set to go again
